Andhra Pradesh removes the DISCOM from the approval path for rooftop solar that never exports, and drops the surcharge with it

Permission to install has rarely been the binding constraint on Indian rooftop solar. The constraint is the DISCOM's seat in the approval chain, where feasibility study, line clearance and sanction each let a utility whose revenue comes from selling the unit decide how long a consumer waits to stop buying it. Removing that seat for systems that never touch the grid is the rare case where the argument is technically unanswerable as well as commercially convenient: a feasibility study examines what an injection does to a feeder, and a plant required to inject zero presents no injection to study. The utility keeps what it needs to run a network, namely intimation, diagrams and inverter telemetry, and loses what it was using to protect a revenue line. The surcharge exemption is the larger change and it is about ownership rather than permission, because cross-subsidy and additional surcharges are how a DISCOM recovers what it loses when a large consumer leaves, and waiving them for third-party-financed captive rooftop makes the developer-owned model viable without the consumer carrying an exit charge. The reason to hold it carefully is the instrument: a practice direction is an interpretive act rather than a notified regulation, faster to issue and easier to revisit, and it currently reaches the market only through trade summaries.

Andhra Pradesh removes the DISCOM from the approval path for rooftop solar that never exports, and drops the surcharge with it

APERC has issued practice directions on behind-the-meter captive solar: no prior permission, no feasibility study, no line clearance, no cross-subsidy surcharge, and zero injection at all times.

The Andhra Pradesh Electricity Regulatory Commission has issued practice directions on the establishment, interconnection, synchronisation and operation of behind-the-meter solar rooftop photovoltaic captive generating plants, reported by RenewEdge on 20 August 2026 and by two other trade outlets the day before and the day after. A consumer installing such a plant for captive consumption may now use multiple interconnections without obtaining prior permission, feasibility approval or line clearance from the distribution company, and may configure multiple inverters according to load and chosen voltage levels.

Three conditions survive. Prior intimation to the concerned DISCOM remains mandatory before interconnecting or islanding the plant, accompanied by technical information including installed capacity and single-line diagrams, according to SolarQuarter. The consumer must ensure zero power injection into the grid at all times while synchronising internal loads that are connected to the grid, irrespective of whether the grid is live or switched off. And data from all installed inverters must be integrated and transmitted to the DISCOM or the State Load Despatch Centre as required, per Energetica India, which also reports that any dedicated line must comply with Section 54 of the Electricity Act, 2003.

The commercial half is the surcharge treatment. Behind-the-meter installations will not attract cross-subsidy surcharge or additional surcharge, and the exemption is reported to extend to projects developed through third-party investment or external financing models under APERC Regulation 4 of 2023, provided the applicable captive consumption conditions are met and nothing is injected during synchronisation. Consumers remain liable for regulated capacity charges determined by the Commission and for standard retail tariff charges, and DISCOMs may seek specific service charges through future tariff filings with justification.

SolarQuarter reports that the directions followed representations from stakeholders under the Eastern Power Distribution Company of Andhra Pradesh, who had reported delays and administrative difficulties. That is the most useful sentence in the coverage: this is a commission responding to a complaint about its own approval chain.

[UNVERIFIED: the number and date of the practice directions. None of the three reports gives either, and RenewEdge states the decision date is not specified. The instrument was not retrieved from APERC.] [UNVERIFIED: the detailed conditions of the surcharge exemption and its scope. Reported consistently by RenewEdge, SolarQuarter and Energetica India, and not confirmed against any APERC document.] [NEEDS DATA: what "captive consumption conditions" means in the direction's own wording, and whether it imports the ownership and consumption tests that the Electricity Rules apply to captive generation.] [NEEDS DATA: whether the exemption reaches existing third-party-financed systems or only new ones.]

What this is not, on the evidence available, is the wider reform package APERC put out in draft in August 2025, which proposed virtual net metering for housing societies, group net metering across one prosumer's several connections, and formal recognition of DER aggregators. Nothing in the August 2026 coverage says those have been notified, and they should not be described as in force.

Why it matters

Permission to install has rarely been the binding constraint on Indian rooftop solar. The constraint is the DISCOM's seat in the approval chain. Feasibility study, line clearance, sanction: at each step a utility whose revenue comes from selling the unit decides how long a consumer waits to stop buying it. The incentive is not hidden and it does not need to be malicious to be decisive. A queue is enough.

Removing that seat for systems that never touch the grid is the rare case where the argument is technically unanswerable as well as commercially convenient. A feasibility study examines what an injection will do to a feeder. A behind-the-meter plant that is required to inject zero at all times presents no injection to study. The DISCOM's remaining interests are safety and visibility, and the directions keep both: intimation before synchronising, single-line diagrams, inverter telemetry to the DISCOM or the load despatch centre. The utility keeps what it needs to operate a network and loses what it was using to protect a revenue line.

The surcharge exemption is the larger change, and it is about ownership rather than permission. Cross-subsidy surcharge and additional surcharge are the instruments through which a DISCOM recovers what it loses when a large consumer leaves its supply. Waiving them for third-party-financed captive rooftop alters who can put capital into a commercial or industrial roof: the developer-owned model becomes viable without the consumer carrying an exit charge on power it generates on its own premises and never sells. For a firm with several connections or dispersed facilities, the multiple-interconnection clarification and the surcharge exemption together are the difference between a pilot on one roof and a portfolio.

The reason to hold all of this carefully is the instrument. A practice direction is an interpretive act, not a notified regulation. It is faster, which is why it exists here, and it is more easily revisited, which is why a developer raising money against it should read it rather than read about it. The document itself is the thing to obtain, and at the time of writing it reaches the market only through trade summaries.

India context

The cross-subsidy surcharge exists because Indian retail tariffs are cross-subsidised: industrial and commercial consumers pay above cost so that agricultural and low-slab domestic consumers pay below it. When a paying consumer self-supplies, the subsidy burden does not disappear, it redistributes onto whoever remains. That is the honest objection to this order, and it is not a DISCOM talking point. The counter-argument is that a surcharge levied on generation consumed behind the consumer's own meter is a charge on not buying something, which is a different thing from a charge for using a network. [NEEDS DATA: the cross-subsidy surcharge and additional surcharge rates currently applicable to commercial and industrial consumers in Andhra Pradesh, to size what has been waived.] [NEEDS DATA: the number of third-party-financed behind-the-meter commercial and industrial systems in the state.]

What's still unknown

  • The practice directions themselves: number, date, and full text. The single most important gap.
  • Whether the directions were accompanied or preceded by a notified amendment to Regulation No. 4 of 2023, or stand alone.
  • Whether virtual net metering, group net metering and aggregator recognition from the August 2025 draft have been notified.
  • What enforcement attaches to the zero-injection requirement, and how it is measured.
  • The DISCOMs' position, and whether any has sought review.
  • Whether this and the reported early-August 2026 single-phase 5 kW exemption in Andhra Pradesh are the same instrument. They are treated here as separate on the basis of differing reported dates and subject matter, which is not confirmed.
